The commit 292b293 creates the MSM boot failures, so squash
the commit 28af690 with it to avoid such failures. The commit ddd847
and 0c1991 are required to keep the watchdog and Copper targets working.

ARM: gic: consolidate PPI handling
PPI handling is a bit of an odd beast. It uses its own low level
handling code and is hardwired to the local timers (hence lacking
a registration interface).
Instead, switch the low handling to the normal SPI handling code.
PPIs are handled by the handle_percpu_devid_irq flow.
This also allows the removal of some duplicated code.

ARM: gic, local timers: use the request_percpu_irq() interface
This patch remove the hardcoded link between local timers and PPIs,
and convert the PPI users (TWD, MCT and MSM timers) to the new
*_percpu_irq interface. Also some collateral cleanup
(local_timer_ack() is gone, and the interrupt handler is strictly
private to each driver).
PPIs are now useable for more than just the local timers.
Additional testing by David Brown (msm8250 and msm8660) and
Shawn Guo (imx6q).

Fix the following warning seen while linking
WARNING: vmlinux.o(.text+0xc4b8): Section mismatch in reference
from the function arch_timer_register() to the (unknown reference)
.cpuinit.data:(unknown)
The function arch_timer_register() references
the (unknown reference) __cpuinitdata (unknown).
This is often because arch_timer_register lacks a __cpuinitdata
annotation or the annotation of (unknown) is wrong.

Level triggered interrupt is deasserted when a new TVAL is written
only when the interrupt is unmasked. Make sure that the interrupt
is unmasked in CTL register before TVAL is written.

Register interrupts using interrupt action mechanism instead of
gic_request_ppi() which is dependent on an another patch series
that doesn't exist yet.
Add read_current_timer() to support ARCH_HAS_READ_CURRENT_TIMER
and register the delay loop routine.

Provide an A15 sched_clock implementation using the virtual counter,
which is thought to be more useful than the physical one in a
virtualised environment, as it can offset the time spent in another
VM or the hypervisor.

Add support for the A15 generic timer and clocksource.
As the timer generates interrupts on a different PPI depending
on the execution mode (normal or secure), it is possible to
register two different PPIs.
